Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair styling composition used as a hair styling material such as a hair cream, a hair setting gel, a hair spray, a foam hair styling material, or as a base thereof. The present invention relates to a hair styling composition which imparts suppleness and good luster to hair while having an improved hair setting effect, and is excellent in shampoo removal properties (the property of being quickly removed by shampooing and hardly remaining on hair). It is.

[0002]

2. Description of the Related Art Hair styling materials are used for preparing and maintaining hair in a desired shape, and there are various forms such as spray type, lotion type, cream type, gel type and mousse type. These hair styling materials use various hair fixing polymers having properties such as anionic, nonionic, amphoteric, and cationic as a setting agent, and these are dissolved in a solvent such as water or a lower alcohol to form a skeleton. It is made by appropriately mixing a surfactant, a thickener, and optionally a propellant.

[0003]

However, when such a hairdressing composition contains a large amount of a hair fixing polymer in order to enhance the hair setting effect, the hair becomes stiff and can be set into a free hairstyle (hair arrangement). ), It was difficult to obtain good quality as a product, for example, it was difficult to remove the hair and the hair-removing property was poor (removal by the hair-washing was not sufficient and remained on the hair). On the other hand, if the amount of the polymer for fixing the hair is reduced in order to obtain the stiffness of the hair, the ease of hair arrangement, the ease of hair washing, etc., a satisfactory setting effect can be obtained. And it was difficult to obtain sufficient quality as a hairdressing agent. Further, when an oil agent is added for the purpose of imparting suppleness or luster to the hair, the setting force tends to decrease, so that it is difficult to increase the compounding amount of the oil agent. It has been difficult to apply suppleness and luster with an oil agent. Therefore, while having a high hair setting effect, it is desired to develop a hair styling composition which imparts suppleness and luster to hair without impairing it, and is easily removed at the time of washing, and hardly remains on hair. Was.

[0004]

[Means for Solving the Problems] In view of such circumstances,
The present inventors have conducted intensive studies to overcome the above-mentioned drawbacks, and as a result, it has been found that, if an alkali salt of polyacrylic acid, a hair fixing polymer, a higher alcohol, and a specific oil agent are used in a specific amount in combination, a good hair can be obtained. The present invention has been found to provide a hair styling composition that imparts a supple feel and a good luster to hair without impairing the set effect and that has good hair washability, and based on this finding. Was completed.

That is, the present invention provides the following components (A) to
(D), (A) Alkali salt of polyacrylic acid 0.005 to 0.5.
1% by weight (B) 0.1 to 5% by weight of a hair fixing polymer (C) 0.1 to 10% by weight of a higher alcohol (D) 5 to 50% by weight of a liquid oil at room temperature selected from esters and triglycerides It is a hairdressing composition characterized by doing.

Hereinafter, the present invention will be described in detail. The alkali salt of polyacrylic acid as the component (A) used in the present invention is an alkali salt of an acrylic acid homopolymer, and is one type of hydrophilic polycarboxylate having high viscosity in an aqueous solution. The alkali salt of polyacrylic acid is a compound usually used in cosmetics and foods as a thickener, an emulsion stabilizer and the like. In the hairdressing composition of the present invention, the alkali polyacrylate of component (A) is used. By using the salt and the component (B) for fixing the hair in combination, a synergistically high setting force can be obtained, and the stiffness of the hair can be reduced.

If it is less than 0.1%, it is not possible to impart sufficient suppleness to the hair, and if it exceeds 10%, the system becomes too hard and spreads poorly, making it difficult to stretch on the hair at the time of use. Arrangement becomes difficult.

The component (D) used in the present invention is an oil agent at room temperature which is selected from esters and triglycerides. In the present invention, a gloss is imparted to the hair in the presence of the components (A) to (C). It has the effect of doing. Normally, various oils such as liquid paraffin, silicone oil, and fatty acid are used in hair cosmetics. In the present invention, a relatively high polarity oil selected from esters and triglycerides is used to make the hair sticky. It can give the hair a shine while maintaining a natural feel without any.
